Browser based apps generally struggle to function well offline (this is also true of certain native apps, but that's a whole other discussion). Using the PWA "toolbox" you can have in-browser apps stored locally via service workers so that they work without needing to fetch anything via the internet.

It's rather useful, and can provide a much better user experience, especially when you have a patchy network.

What’s an example of a large tech product that functions as a PWA that users really love?

[osrec]

There's Twitter's PWA, which isn't too bad in my opinion.

My product has approx 300k users and is a PWA: https://usebx.com - our users seem to like it :)

If you don’t mind me asking, how does your product make money?

[osrec]

We have a quota on the number of documents you can create, after which you must subscribe. It's a very generous quota, but we still have a good number of people subscribing.

Our major income comes from larger corporate contracts with medium to large businesses, that deploy our product on-prem. Often these were people who used our SaaS product, liked it, and asked us to deploy it internally for their business. Much less hassle than running a company that's purely SaaS based, and more stable income!

I don’t know if meets the condition of “users really love,” but don’t Google Docs have the capability of functioning as an offline PWA?

Dunno about "really love" anymore, but gmail?
